Detailed Description

The Delphi FP10514 is a fuel injection pressure regulator engineered to maintain consistent fuel pressure in the injection system. Proper pressure regulation supports accurate fuel delivery, which is important for drivability and fuel system performance in vehicles such as the Dodge Daytona, Dodge Spirit, Chrysler LeBaron, and related 1988 Chrysler and Dodge platforms. This part cross-references Dorman OE Solutions 800-121 for the same application.

As an OE-focused replacement part, the FP10514 is built around Delphi’s long history supplying original equipment to major automakers. The metal housing, push-in inlet, hose outlet, and bolt-mount layout make it a practical service part when replacing a worn or failing regulator on the listed fitments.

What It Helps Address

• Fuel pressure that is too high or too low
• Hard starting caused by unstable fuel delivery
• Rough idle related to pressure regulation issues
• Fuel smell or rich-running symptoms from regulator failure
• Driveability concerns on fuel-injected Chrysler, Dodge, and Plymouth vehicles

Installation Notes and Tips

Verify inlet and outlet port sizes, mounting style, and system pressure before installation. Confirm the vehicle uses the listed push-in inlet and hose outlet configuration, and inspect fuel lines and seals for wear during replacement. For fitment reference, this part fits 1992-1993 Dodge Daytona, 1988 Dodge Daytona, 1992 Dodge Spirit, 1988 Chrysler LeBaron, 1988 Chrysler New Yorker, 1988 Chrysler Town & Country, 1988 Dodge 600, 1988 Dodge Lancer, 1988 Dodge Shadow, and 1988 Plymouth Sundance.

Quality Assurance

Delphi builds aftermarket fuel system parts using OE experience and engineering knowledge developed through decades of original equipment supply. The FP10514 follows that OE-based approach for the listed applications.
